In an email that has been circulated far and wide, Winston Chen, the developer of Voice Dream Reader, has discussed what will be coming in version 4 of the app on iOS. The new update, which has been submitted to Apple, contains support for 3D touch actions on the iPhone 6S and 6S plus, a new mode called Pac-Man reading mode, finger reading, and scanning. Scanning allows you to do a firm press on the fast forward button to double the speed of the reading voice. Releasing the 3D touch will return you to the speed you were at before performing the 3D touch. This is an iOS only update, there was no indication as to the state of development on the Android platform. The portion of the email describing the new features has been added below.

It's out now. I updated last night. It took a while to upgrade my enormous library, but it went fine. Luckily, iCloud Drive sync is turned off by default. So far, the thing I'm liking most is the ability to use Alex to read my text files. Much appreciated.
